Ben Skeggs 34508f9d26 drm/nouveau/kms/nv50-: determine MST support from DP Info Table

Ben Skeggs 11e451e740 drm/nouveau: remove fence wait code from deferred client work handler 
Fences attached to deferred client work items now originate from channels
belonging to the client, meaning we can be certain they've been signalled
before we destroy a client.

This closes a race that could happen if the dma_fence_wait_timeout() call
didn't succeed.  When the fence was later signalled, a use-after-free was
possible.

Ben Skeggs 470db8b781 drm/nouveau/gem: tie deferred unmapping of buffers to VMA fence completion 
As VMAs are per-client, unlike buffers, this allows us to avoid referencing
foreign fences (those that belong to another client/driver) from the client
deferred work handler, and prevent some not-fun race conditions that can be
triggered when a fence stalls.

The algorithm for GM200 and newer matches RM for all the boards I have, but
I don't have enough data to try and figure something out for earlier boards,
so these will still write zeroes to the table as we did before.

Ben Skeggs 43952c6f43 drm/nouveau/gr/gf100-: virtualise alpha_beta_tables + improve algorithms 
I haven't yet been able to find a fully programatic way of calculating the
same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends
on data tables for specific configurations.

I couldn't find traces for every possibility, so the algorithm will switch
to a mapping similar to what GK104-GM10x use if it encounters one.  We did
the wrong thing before anyway, so shouldn't matter too much.

The algorithm used in the GK104 implementation was ported from NVGPU.

Ben Skeggs 4f2fc25c0f drm/nouveau/fifo/gk104-: poll for runlist update completion 
Newer HW doesn't appear to send this event, which will cause long delays
in runlist updates if they don't complete immediately.

RM doesn't use these events anywhere, and an NVGPU commit message notes
that polling is the preferred method even on HW that supports the event.

Ben Skeggs a7cf01809b drm/nouveau/fifo/gk104-: require explicit runlist selection for channel allocation 
We didn't used to be aware that runlist/engine IDs weren't the same thing,
or that there was such variability in configuration between GPUs.

By exposing this information to a client, and giving it explicit control
of which runlist it's allocating a channel on, we're able to make better
choices.

The immediate effect of this is that on GPUs where CE0 is the "GRCE", we
will now be allocating a copy engine running asynchronously to GR for BO
migrations - as intended.

Ben Skeggs c5c9127b25 drm/nouveau/device: implement a generic method to query device-specific properties 
We have a need to fetch data from GPU-specific sub-devices that is not
tied to any particular engine object.

This commit provides the framework to support such queries.
